Law and Investigation Dept Dept of law and investigation Threatened me with a lawsuit "against my name and social security number Homestead, Florida

I have been getting phone calls from this outfit, the man first identified himself as "Dennis Peterson" and now Officer Terin or Terrance Black, although he is most definitely from India.  He told me that I should have my attorney call him, I told him I do not have an attorney, nor do I need one.  He then asked me to hold on, and gave the call to some other person, but I swear it was still him on the line.  He told me that he was going to tell me what I needed to know, and that I was not to interrupt him until he was finished.  Since I could not understand anything he was saying i hung up on him.  He called back and left a voice mail message repeating himself all over again.
